A nickel-cadmium battery has been developed that can be operated at 80% depth of discharge in excess of 10 (possibly 15) years in a geosynchronous orbit application, having about a 30% weight saving per spacecraft over state-of-the-art nickel-cadmium batteries when used with a 1000 W eclipse load. The approach used in the development was to replace nylon separators with inert polymer-impregnated zirconia, to use electrochemically deposited plates in place of conventional chemically precipitated ones, and to use an additive to extend negative plate lifetime. The design has undergone extensive testing using both engineering and protoflight cell configurations
